摘要: A level (100) includes a light source (10) and a cone-shaped reflecting element (40) with reflecting surface for reflecting light beam from the light source to produce a circumferential leveling plane. The light source is arranged adjacent to the peak of the cone-shaped reflecting element, and on the center axis of the cone-shaped reflecting element.
